How to Block North Korean Hackers: Easy Steps to Protect Your Data in 2026

You Might Think Hackers Only Go After Big Companies—But Here’s the Truth

Last month, my cousin got a text from "Amazon" saying her package was delayed. She clicked the link, entered her password, and within hours, her bank account had three weird charges. Turns out, it wasn’t Amazon at all—it was a scam linked to North Korean hackers.

If this sounds like something that could happen to you, you’re not alone. In 2026, nearly half of U.S. tech breaches are tied to North Korean cybercriminals, according to cybersecurity firms. The scary part? They’re not just targeting governments or corporations. They’re going after everyday people—students, remote workers, travelers—anyone with an unlocked digital door.

The good news? You don’t need a cybersecurity degree to fight back. In this guide, I’ll show you simple, free (or cheap) ways to lock your devices, spot scams, and use tools like VPNs to stay safe. No tech expertise required.

Lock Down Your Devices Like a Pro (No Geek Skills Needed)

You wouldn’t leave your front door wide open when you leave the house. So why leave your phone or laptop unprotected? Hackers exploit weak spots—like outdated software or weak passwords—to sneak in. Here’s how to shut them out.

Update Everything, Automatically

Hackers love old software because it’s full of known vulnerabilities—like a window left unlocked. Turning on auto-updates for your phone, laptop, and apps closes those gaps without you having to think about it.

Example: The 2021 Colonial Pipeline hack, which caused gas shortages across the U.S., happened because of one unpatched password. Don’t let that be you.

How to do it:

• On iPhone: Go to Settings > General > Software Update and turn on Automatic Updates.
• On Android: Go to Settings > System > Advanced > System Update and enable auto-updates.
• On Windows: Go to Settings > Update & Security > Windows Update and select Automatic.
• On Mac: Go to System Settings > General > Software Update and check Automatically keep my Mac up to date.

Passwords: Ditch "123456" for a Password Manager

If you’re still using "password123" or the same password for everything, you’re basically handing hackers the keys to your digital life. A password manager is like a vault for your passwords—it generates strong, unique passwords and remembers them for you.

Analogy: Would you use the same key for your house, car, and mailbox? No? Then don’t reuse passwords.

How to do it:

1. Download a free password manager like Bitwarden or 1Password.
2. Let it generate strong passwords for your accounts (e.g., 7x!9@Lp#2$vQ).
3. Use the password manager to autofill logins so you don’t have to remember them.

Pro tip: Start with your email and banking passwords—those are the most valuable to hackers.

Two-Factor Authentication (2FA): Your Digital Bodyguard

2FA adds an extra layer of security by requiring a second code (usually sent to your phone) when you log in. Even if a hacker steals your password, they can’t get in without that code.

Example: In 2023, a hacker tried to break into my Gmail account. Thanks to 2FA, I got a text with a code, and the hacker was locked out.

How to do it:

1. Go to your account settings (e.g., Gmail, Facebook, or your bank).
2. Look for Security or Two-Factor Authentication and enable it.
3. Choose SMS (text message) or an app like Google Authenticator or Authy.

Why apps are better than SMS: Hackers can intercept text messages, but app-based codes are much harder to steal.

Spot Phishing Scams Before They Hook You

Phishing is when hackers trick you into giving up your passwords, credit card numbers, or other sensitive info. They might send an email pretending to be Amazon, your bank, or even a friend. North Korean hackers are especially good at this—they’ll impersonate trusted companies to steal your data.

The "Too Good to Be True" Rule

If an email, text, or DM promises free money, a "missed delivery," or an "urgent security alert," it’s probably a scam. Hackers rely on urgency and fear to trick you into clicking.

Example: Earlier this year, North Korean hackers sent fake "Apple ID suspension" emails. Victims who clicked the link were taken to a fake login page that stole their passwords.

Analogy: Would a stranger hand you $100 on the street? No? Then why would a prince email you about an inheritance?

Check the Sender’s Email Address

Hackers can make emails look real, but the sender’s address is a dead giveaway. Hover over the sender’s name to see the real email.

Red flags:

• Typos (e.g., support@amaz0n.com instead of support@amazon.com).
• Weird domains (e.g., apple-security@random-site.ru).
• Urgent demands ("Your account will be deleted in 1 hour!").

When in Doubt, Call the Real Company

If you get a suspicious message, don’t click any links. Instead, look up the company’s official phone number (don’t use the one in the email) and call them to ask if it’s legit.

Example: My friend got a text from "Netflix" saying her payment failed. She called Netflix’s real customer service number and found out it was a scam.

Public Wi-Fi: How to Use It Without Getting Hacked

Public Wi-Fi is convenient, but it’s also a hacker’s playground. When you connect to a network at a coffee shop, airport, or hotel, hackers can "eavesdrop" on your activity—like someone listening to your phone call in a café.

Assume Public Wi-Fi Is a Hacker’s Playground

Never log into banking, email, or work accounts on public Wi-Fi. Hackers can steal your passwords, credit card numbers, and even your location.

Example: A hacker at a coffee shop once stole 50+ passwords in an hour using a $20 tool. All it took was one unprotected connection.

Use a VPN: Your Invisible Shield

A VPN (Virtual Private Network) encrypts your data so hackers can’t read it. Think of it like sending your mail in a locked box instead of a postcard.

How it works: When you connect to a VPN, your internet traffic is routed through a secure server, hiding your activity from prying eyes.

How to do it:

1. Download a VPN app like ProtonVPN (free option available) or NordVPN.
2. Open the app and connect to a server (any location will do).
3. Now you can browse safely on public Wi-Fi.

Free option: Some browsers, like Opera, have built-in VPNs for basic protection.

Turn Off Auto-Connect

Disable "auto-join" for Wi-Fi networks so your phone doesn’t connect to fake hotspots set up by hackers.

Example: Hackers often create networks like "Free Airport Wi-Fi" to trick people into connecting. Once you’re on, they can steal your data.

How to do it:

• On iPhone: Go to Settings > Wi-Fi and turn off Auto-Join Hotspot.
• On Android: Go to Settings > Network & Internet > Wi-Fi > Wi-Fi Preferences and turn off Auto-connect to open networks.

Extra Layers of Protection (Because Hackers Are Persistent)

Hackers are always looking for new ways to break in. Here are a few extra steps to keep them out.

Freeze Your Credit: The Nuclear Option for Identity Theft

If a hacker gets your Social Security number, they can open credit cards or loans in your name. Freezing your credit blocks them from doing this.

Analogy: It’s like putting your credit report in a safe.

How to do it:

1. Go to Experian, Equifax, or TransUnion.
2. Look for Credit Freeze and follow the steps.
3. It’s free and takes about 10 minutes.

Bonus: You can unfreeze it anytime if you need to apply for a loan or credit card.

Backup Your Data: The "Oops, I Got Hacked" Safety Net

Ransomware attacks (like WannaCry) lock you out of your files and demand payment to get them back. Backing up your data means you won’t lose everything if this happens.

Example: In 2024, a ransomware attack hit a hospital, locking doctors out of patient records. Backups saved the day.

How to do it:

1. Use cloud backups like Google Drive or iCloud.
2. Or, use an external hard drive for offline backups.

Check If Your Data’s Been Leaked

Hackers often sell stolen data on the dark web. You can check if your email or phone number is out there using Have I Been Pwned.

How to do it:

1. Go to Have I Been Pwned.
2. Enter your email or phone number.
3. If it’s been leaked, change those passwords ASAP.

What to Do If You Think You’ve Been Hacked

If you suspect you’ve been hacked, don’t panic. Here’s what to do:

Change Passwords Immediately

Start with your email and banking passwords—those are the most valuable to hackers. Use a password manager to generate new, strong passwords.

Run a Malware Scan

Use a free tool like Malwarebytes or Windows Defender to scan your device for malware.

Report It

File a report with the FTC or IC3 (for cybercrimes). Reporting helps authorities track hackers, including groups like North Korea’s Lazarus Group.

Monitor Your Accounts

Check your bank statements and credit reports for weird charges. Even a $1 charge could be a hacker testing your card.
